How do I Install external APKs necessary for my app in the Eclipse ADT?

I need to rely on external app (Barcode scanner in my case). The eclipse emulator crashes when I try to download it from within the emulator itself.

• Is there a way to download it using the emulator?
• Or Is there a way to directly install the APK and make it available for my application?

I ran the emulator from eclipse.

Check to see if the device is detected using :>adb devices

I ran the adb install foo.apk

This installed the APK in the emulator.

• If the Command prompt says no AVD, you will need to create one >android create avd -n <avd-name> -t 2

• Installing the apk in the tools is considered the best practice
